The objective of this study was to determine the effects of topical 0.5% tropicamide, 1% atropine sulphate and 10% phenylephrine hydrochloride ophthalmic solutions on intraocular pressure (IOP) and horizontal pupil diameter (HPD) in the dog during the first hour after treatment. Forty clinically and ophthalmologically normal canine patients (between the ages of 2 and 6 years) of varying breed a...

The purpose of this project was to test the hypothesis that baroreceptor modulation of muscle sympathetic nerve activity (MSNA) and heart rate is altered during the cold pressor test. Ten subjects were exposed to a cold pressor test by immersing a hand in ice water for 3 min while arterial blood pressure, heart rate, and MSNA were recorded. During the second and third minute of the cold pressor...

PURPOSE We tested the hypothesis that changes in accommodation after instillation of Phenylephrine Hydrochloride (PHCl) observed in some studies could be caused by changes in optics. METHODS We performed two experiments to test the effects of PHCl on static and on dynamic accommodation in 8 and 6 subjects, respectively. Objective wavefront measurements were recorded of the static accommodatio...

IN ophthalmic practice, drugs such as hydroxyamphetamine hydrobromide (Paredrine) and phenylephrine hydrochloride (Neosynephrine) are commonly used to produce mydriasis without alteration of refractive state. There is, however, no definite evidence that the refractive state is completely unaffected by these drugs, and experimental information on this subject is limited. Of some interest in this...

Paroxysmal nonepileptic events are episodic changes in behavior, sensation, or consciousness that similar to epileptic seizures but not associated with abnormal ictal brain electrophysiological discharges. Here, a case treated as seizure was presented order draw attention paroxysmal differential diagnosis.
 A 4 years old girl sent our hospital the diagnose of status epilepticus due change ...

ABSTRACT. For the first time, silver nanoparticles (AgNPs) were fabricated with graphite pencil electrode (GPE) by immersing a bare hard black (HB pencil) in AgNO3 solution mixed extract Quercus infectoria solution, followed placing directly against to UV lamp (254 nm) and kept for 30 min. Silver modified-GPEs characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dis...
